OIL-GAS BURNER.

Specification of Letters Patent.

Patented Nov. 3@, 1915.

Application filed Septemberll, 19.15. Serial No. 50,281.

To all whom it may concern:

Be it known that 1, ROBERT BLUMBERG,.

a citizen of the United States, and a resident of the city of New York, Flushing, borough of Queens, in the county of Queens and State of New York, have invented a new \and Improved Oil-Gas Burner, of which the following is a full, clear, and eXact description. This invention relates to heating apparatus and has particular reference to appliances for burning liquid fuel.

Among the objects of the invention is to provide an improved device for use in all makes or styles of stoves, heaters, ranges, furnaces and boiler heaters, means being 1 provided to convert the present heating ap- "pliances, wherecoal, coke, wood or the like are used, into fuel oil burners with a corresponding economy of fuel cost and increase of convenience and efliciency.

. Another object of the invention is to provide a burner adapted for the use of all kinds or grades of oils and especially the cheaper and unrefined varieties of oils, the

device being found in practice well adapted for the burning of cheap distillates from gas factories or the like.

With the foregoing and other objects in view, the invention consists in the arrangement and combination of parts hereinafter described and claimed, and while the invention is not restricted to the exact details of construction disclosed herein, still for thepurpose of illustrating a practical embodiment thereof reference is had to the accom .panying drawlngs, in which like reference "characters designate the same parts in the several views, and in which Figure 1 is a perspective view showing the main parts ofthedevice in operative po- ..sition, the second diffuser being omitted;

" Fig. 2-is a vertical longitudinal Section on the line 22 of Fig. 3; Fig. 3 is avertical transverse section on the line 3-3 of Fig. 2; Fig. 4c is a plan view with the air drums .and diffusion members removed and showing the auxiliary air pipe in horizontal section; and Fig. 5 is a sectional detail on the line 5.5-,0f Fig. 2;

Referring now more particularly to the I v drawings, l-show a rigid base 10 of cast metalor the like and shown herein as of substantially rectangular form. This base is provided at its ends with vertical openings 11 through which air is supplied to the combustion chamber from beneath the base. The main portion of the base surrounding these openings comprises a vertically arranged rim having on its inner wall an inwardly projecting rib 12. The rib, however, merges into the vertical end walls 13 of a centrally disposed oil well 1% having a closed bottom and bounded on its ends and sides by said walls 13 and the main rim of the base. The lower portion of the rim serves to support the burner device as a whole at suificient elevation above the stove or other heater grate to provide ample flow of air throughthe grate and through the openings 11; The upper edge or portion of the rim in'connection with the rib 12 provides seats for the air drums 15, the lower edges of the drums resting upon the ribs and requiring, therefore, no bolts, screws or other fastening devices to hold them in position.

At 16 is a cup having a central vertical nozzle 17. The cup is located in the oil well 14: and into the lower endof the nozzle is. fitted an oil supply pipe 18 projecting through the bottom of the oil well. as shown in Fig. 2. This pipe 18 constitutes a means, therefore, for holding the cup securely in position. The nozzle 17 is preferably shorter than the height of the cup and the oil delivered into the cup is ignited, and the cup becoming heated causes the vaporization of the oil, the vapor becoming mixed with air passing upwardly through the openings 11. The cup is formed with a notch 16"at one side whereby any excess or overflow of oil from the nozzle filling the cup will flow into the well outside of the cup and will be consumed therein without wast-- of the walls 15 and 15 rest within the rim of the base and upon the rib 12. The inner edges of the side walls 15 are vertical and lit snugly against the outer surfaces of the walls 13. Each air drum also includes a narrow horizontal lip 20 at the top extending across toward the corresponding lip of the other member. A diffusion plate 21 extends from one lip 20 to the other. This plate 21 is provided with rabbeted ends fit-.--

ting snugly upon the edges of the lips and is strengthened by a strap 22 of a hinge pivoted at 23 to one of the lips 20. The opposite end of the strap 22 is adapted to nest snugly between a pair of lugs 24 on the other lip whereby the plate 21 is effectively held in position.

The structure between the air drums and beneath the diffusion plate 21 is practically open above the base rim whereby openings 25 are formed on the two sides of the structure and through which openings the products of combustion emerge. The primary combustion takes place beneath the diffusion plate 21 at the place where the fresh air ad mitted upwardly through the air drums mixes with the vapor formed with the vaporization of theoil in or about the cup 16. The plate 21 being hinged as indicated provides for free access to the cup and nozzle for any purpose such as igniting or initiating the operation of the burner. Either or both of the air drums 15, however, may be removed from the base, if desired, at any time.

Under certain conditions depending upon the character of oil employed or other circumstances, an auxiliary fresh air supply is provided, and it comprises a vertical pipe 26 fitted in the base preferably through the bottom of the oil well and having a horizontal perforated pipe 27 secured to its up-.

per end. The perforations are indicated at 27 and 27 on the inner side and bottom respectively. The air delivered upwardly through the pipe 26 being in close proximity to the main flame is heated and jets forcibly laterally through the ports 27 for mixing with the flame or products of combustion on the opposite side of the burner. The air through the series of ports 27 mixes with the products of combustion on the near side of the burner. This auxiliary air augments the intensity of the heat and renders it impossible for any fuel value to be wasted.

At 28 is indicated another diffuser supported upon legs 29 having feet 30 resting upon the inclined walls 15 of the air drums and hence bent at an angle to the main portions of the legs. The diffuser 28 is in the nature of a plate slightly concaved or depressed in its center. All of the combustion takes place below this diffuser and the heat and other products of combustion are defiected laterally so as to be well dispersed and hence brought into contact with a large area to be heated.
